    mkdir targetDir
    for /r %x in (*.dll, *pdb) do copy &quot;%x&quot; targetDir\

Use /Y at the end of the above command if you are copying multiple files and don&#39;t want to keep answering &quot;Yes&quot;. 



**command XCOPY**

example of copying folder recursively:

    mkdir DestFolder
    xcopy SrcFolder DestFolder /E

(as stated below in the comment following [WIKI][1] that command was made available since DOS 3.2)


  [1]: http://en.wikipedia.org/wiki/List_of_MS-DOS_commands#XCOPY

Make sure that you have the quotes right if you have spaces in your path.

This is my postbuild event for my TFS build server (that is why there is &quot;%%&quot;). I needed all the test files to be copied over. 


    if not exist  &quot;$(TargetDir)..\SingleFolderOutput&quot; mkdir -p &quot;$(TargetDir)..\SingleFolderOutput&quot;

    for /r **%%x** in (*.dll, *.pdb, *.xml, *.xaml, *.exe, *.exe.config) do xcopy **&quot;%%x&quot;** &quot;$(TargetDir)..\SingleFolderOutput&quot; /Y

For gathering PBD files I end up with this:

    cmd /q /c for /R &quot;&lt;your_source_folder&gt;&quot; %f in (*.pdb) do xcopy &quot;%f&quot; &quot;&lt;your_destination_folder&gt;&quot; /I /Y

    @echo off
    if %1&#39;==&#39; goto usage
    if %2&#39;==&#39; goto usage
    if %3&#39;==&#39; goto usage
    for /D %%F in (%1\*) do xcopy %%F\%2 %3 /D /Y
    for /D %%F in (%1\*.) do call TreeCopy %%F %2 %3
    goto end
    :usage
    @echo Usage: TreeCopy [Source folder] [Search pattern] [Destination folder]
    @echo Example: TreeCopy C:\Project\UDI *.xsd C:\Project\UDI\SOA\Deploy\Metadata
    :end

I&#39;m not aware of any command line tools that do this directly, but you could create a batch script to loop through sub folders, and copy the files you need.

However you may end up with files with duplicate filenames if you place them all in the same folder.

Is there any method?
My computer is AMD64.

    ::std::string str;
    BOOL loadU(const wchar_t* lpszPathName, int flag = 0);

When I used: 

    loadU(&amp;str);

the VS2005 compiler says:

    Error 7 error C2664:: cannot convert parameter 1 from &#39;std::string *__w64 &#39; to &#39;const wchar_t *&#39;

How can I do it?

I&#39;m a recent semi-convert to Eclipse after 20 years of using vi and gvim.  One of the things I miss about gvim is that I could cut a bunch of different snippets of code into named buffers, and paste them at will when doing something like repeating a common idiom.  For instance I&#39;d have it so `&quot;ap` would paste

    DatabaseHandle handle = null;
    try
    {
      handle = DatabaseConnectionPool.newHandle();

and then `&quot;bp` would paste

      handle.commit();
    }
    finally
    {
      handle.rollback();
      DatabaseConnectionPool.returnHandle(handle);
    }

 And I could repeat both of them over and over in the course of a day.  In an answer to another question, somebody mentioned that you could &quot;manage code snippets&quot; in Eclipse, but didn&#39;t mention how.  So now I&#39;m asking: how do you manage code snippets in Eclipse?

I need to echo a string containing angle brackets (&lt; and &gt;) to a file on a Windows machine.  Basically what I want to do is the following:  
`echo some string &lt; with angle &gt; brackets &gt;&gt;myfile.txt`

This doesn&#39;t work since the command interpreter gets confused with the angle brackets.  I could quote the whole string like this:  
`echo &quot;some string &lt; with angle &gt; brackets&quot; &gt;&gt;myfile.txt`

But then I have double quotes in my file that I don&#39;t want.  

Escaping the brackets ala unix doesn&#39;t work either:  
`echo some string \&lt; with angle \&gt; brackets &gt;&gt;myfile.txt`

Ideas?

I have an [EXE][1] file that I should like to sign so that Windows will not warn the end user about an application from an &quot;unknown publisher&quot;. I am not a Windows developer. The application in question is a screensaver generated from an application that generates screensaver applications. As such I have no influence on how the file is generated.

I&#39;ve already found out that I will need a [code signing][2] certificate from a [CA][3] like [Verisign][4] or instantssl.com. What I don&#39;t understand is what I need to do (if at all possible) to sign my EXE file. What is a simple explanation?

Mel Green&#39;s answer took me further, but signtool wants me to specify what certificate to use in any case. Can I get a free code signing certificate somehow to test if this will work for me at all?

Also please specify which certificate kind is the correct one. Most sites only mention &quot;code signing&quot; and talk about signing applications that are actually compiled by the user. This is not the case for me.

As a developer, tools that store configuration/options in the registry are the bane of my life. I can&#39;t easily track changes to those options, can&#39;t easily port them from machine to machine, and it all makes me really yearn for the good old days of .INI files...

When writing my own applications, what - if anything - should I choose to put in the registry rather than in old-fashioned configuration files, and why?



When - and why - should you store data in the Windows Registry?

POSIX environments provide at least two ways of accessing files.  There&#39;s the standard system calls `open()`, `read()`, `write()`, and friends, but there&#39;s also the option of using `mmap()` to map the file into virtual memory.

When is it preferable to use one over the other?  What&#39;re their individual advantages that merit including two interfaces?

When should I use mmap for file access?

I have read the answers for [What&#39;s the best way to check if a file exists in C? (cross platform)](https://stackoverflow.com/questions/230062/whats-the-best-way-to-check-if-a-file-exists-in-c-cross-platform), but I&#39;m wondering if there is a better way to do this using standard c++ libs? Preferably without trying to open the file at all. 

Both `stat` and `access` are pretty much ungoogleable. What should I `#include` to use these?

Is there a way to find the size of a file object that is currently open?

Specifically, I am working with the tarfile module to create tarfiles, but I don&#39;t want my tarfile to exceed a certain size.  As far as I know, tarfile objects are file-like objects, so I imagine a generic solution would work.

Size of an open file object

We had a discussion here at work regarding why _fread()_ and _fwrite()_ take a size per member and count and return the number of members read/written rather than just taking a buffer and size. The only use for it we could come up with is if you want to read/write an array of structures which aren&#39;t evenly divisible by the platform alignment and hence have been padded but that can&#39;t be so common as to warrant this choice in design.

From [fread(3)](https://man7.org/linux/man-pages/man3/fread.3.html):

&gt;The function fread() reads nmemb elements of data, each size bytes long,
&gt;from the stream pointed to by stream, storing them at the location given
&gt;by ptr.
    
&gt;The  function  fwrite()  writes  nmemb elements of data, each size bytes
&gt;long, to the stream pointed to by stream, obtaining them from the location
&gt;given by ptr.
    
&gt;fread() and fwrite() return the number of items successfully read or written
&gt;(i.e., not the number of characters).  If an error occurs, or  the
&gt;end-of-file is reached, the return value is a short item count (or zero).

What is the rationale for fread/fwrite taking size and count as arguments?

I&#39;ve been using the idiom below for some time now. And it seems to be the most wide-spread, at least on the sites I&#39;ve visited.

Is there a better/different way to read a file into a string in Java?

    private String readFile(String file) throws IOException {
        BufferedReader reader = new BufferedReader(new FileReader (file));
        String         line = null;
        StringBuilder  stringBuilder = new StringBuilder();
        String         ls = System.getProperty(&quot;line.separator&quot;);

        try {
            while((line = reader.readLine()) != null) {
                stringBuilder.append(line);
                stringBuilder.append(ls);
            }

            return stringBuilder.toString();
        } finally {
            reader.close();
        }
    }


How do I create a Java string from the contents of a file?

I have a complex command that I&#39;d like to make a shell/bash script of.  I can write it in terms of `$1` easily:

    foo $1 args -o $1.ext

I want to be able to pass multiple input names to the script. What&#39;s the right way to do it?  

And, of course, I want to handle filenames with spaces in them.

How to iterate over arguments in a Bash script

I&#39;ve found the &quot;open&quot; command in Mac OS X very handy in the command line. From &quot;man open&quot;:

&gt; The `open` command opens a file (or a directory or URL), just as if you had
    double-clicked the file&#39;s icon. If no application name is specified, the
    default application as determined via LaunchServices is used to open the
    specified files.

That is, if I want to open a PDF file with the default PDF viewer (happens to be Preview), I only need to do:

    open my.pdf

In Linux, however, to open a PDF file from the command line, I had to dig around to find the default PDF viewer is, for instance, &quot;evince&quot; (who&#39;d have guessed??), and then

    evince my.pdf

So, is there a simple equivalent of the &#39;open&#39; command in the Linux command line?

Thanks!

I&#39;m developing a C++ command-line application in Visual Studio and need to debug it with command-line arguments. At the moment I just run the generated EXE file with the arguments I need (like this `program.exe -file.txt`) , but this way I can&#39;t debug. Is there somewhere I can specify the arguments for debugging?

Debugging with command-line parameters in Visual Studio

I have a single string that contains the command-line parameters to be passed to another executable and I need to extract the string[] containing the individual parameters in the same way that C# would if the commands had been specified on the command-line. The string[] will be used when executing another assemblies entry-point via reflection.

Is there a standard function for this? Or is there a preferred method (regex?) for splitting the parameters correctly? It must handle &#39;&quot;&#39; delimited strings that may contain spaces correctly, so I can&#39;t just split on &#39; &#39;.

Example string:

    string parameterString = @&quot;/src:&quot;&quot;C:\tmp\Some Folder\Sub Folder&quot;&quot; /users:&quot;&quot;abcdefg@hijkl.com&quot;&quot; tasks:&quot;&quot;SomeTask,Some Other Task&quot;&quot; -someParam foo&quot;;

Example result:

    string[] parameterArray = new string[] { 
      @&quot;/src:C:\tmp\Some Folder\Sub Folder&quot;,
      @&quot;/users:abcdefg@hijkl.com&quot;,
      @&quot;tasks:SomeTask,Some Other Task&quot;,
      @&quot;-someParam&quot;,
      @&quot;foo&quot;
    };


I do not need a command-line parsing library, just a way to get the String[] that should be generated.

&lt;strong&gt;Update&lt;/strong&gt;: I had to change the expected result to match what is actually generated by C# (removed the extra &quot;&#39;s in the split strings)
